Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes ia64 libm function implementations use libm_alias_double to define function aliases. The same approach is followed as with the corresponding long double patch: the ia64-specific macros are left unchanged, with calls to libm_alias_double_other being added in most cases and libm_alias_double itself being used in only a few places. Tested with build-many-glibcs.py for ia64-linux-gnu that installed stripped shared libraries are unchanged by the patch. * sysdeps/ia64/fpu/libm-symbols.h: Include <libm-alias-double.h>. * sysdeps/ia64/fpu/e_acos.S (acos): Use libm_alias_double_other. * sysdeps/ia64/fpu/e_acosh.S (acosh): Likewise. * sysdeps/ia64/fpu/e_asin.S (asin): Likewise. * sysdeps/ia64/fpu/e_atan2.S (atan2): Likewise. * sysdeps/ia64/fpu/e_atanh.S (atanh): Likewise. * sysdeps/ia64/fpu/e_cosh.S (cosh): Likewise. * sysdeps/ia64/fpu/e_exp.S (exp): Likewise. * sysdeps/ia64/fpu/e_exp10.S (exp10): Likewise. * sysdeps/ia64/fpu/e_exp2.S (exp2): Likewise. * sysdeps/ia64/fpu/e_fmod.S (fmod): Likewise. * sysdeps/ia64/fpu/e_hypot.S (hypot): Likewise. * sysdeps/ia64/fpu/e_lgamma_r.c (lgamma_r): Define using libm_alias_double_r. * sysdeps/ia64/fpu/e_log.S (log10): Use libm_alias_double_other.
